本文给出一种新的利用前场预测均方误差的帧内ADPCM编码方法,该方法根据五幅典型图象,给出三种预测器,五种量化器的设计参数。由于利用了前场的预测均方误差做为控制信息,因此,该编码方法能够较好地匹配于多种图象源。 In this paper, we propose a new intra-frame ADPCM encoding method that uses the mean square error of the forecourt prediction. The proposed method gives the design parameters of three predictors and five quantizers based on five typical images. Due to the use of the prediction mean square error of the foreground as the control information, the coding method can better match with a variety of image sources.
